Hi got the solution ...
i was trying to include the .h file ... so as to not get undefined ref
when the function name was already in symbol table ... so now when i
include the linker was trying to search the function-name symbol
somewhr outside as it was extern ....

after removing the # include i got the linker linking
properly.
